OIL-BURNER.

Specification of Letters Patent. Patented Nov. 19, 1918.

Application filed March 5, 1918. Serial No. 220,644.

Oakland, in the county of Alameda, State of California, have invented a new and useful Oil-Burner, ofwhich the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to an oil burner especially adapted for use with kitchen stoves although, of course, it may be used other kind of stoves.

An object of the invention is to provide a burner with a considerable length of heating pipes whereby the gas will be delivered to the fire in a perfectly vaporized condition, said heating pipes being filledwith a material which isadapted toassist in transferring the heat from the pipes to the oil to be vaporized.

' Another object of the invention is to pro-- duce a burner which is capable of having one or -m0re blazes while heating the oil adequately for'either of the blazes should only one be used.

Another object of the invention isto produce a series of deflectors to receive the direct flame in order to prevent the heating pipe from becoming too hot and carbonizing the oil.

Another object of the invention is to pro vide a burner which may be used or notat the W111 of with additional deflectors the person operating the stove, the additional deflectors being for' the purpose of directing the flame toward the oven or directing it to heat the top of the stove as may be desired.

Another object of the invention is -'to producea burner which will give the desired heat for all purposes with the smallest fuel consumption.

Another object of the invention is to so construct and locate the heating pipes that the lower pipe assists in protecting the upper heating pipe from the flame thereby increasing the life of the plpes.

Other objects of the invention Wlll appear as the description proceeds.

An'emb0diment of the invention is shown in the drawings in which the same reference. numeral is applied to the same portion throughout, but I am aware that there may be modifications thereof.

Figure 1 isa perspective view of a portion of a stove illustrating the installation therein of its burner, the burner being shown 1n perspective and side elevation,

Flg. 2 is a cross section of one of the burner pipes showing the wires therein which assist in transferring the heat to the fuel.

, Fig. 3 is a side elevation of a portion of one. of the heating pipes, showing one of the deflectors and a portion of the heating wires.

In the drawing the numeral 1 indicates the stove which has suitable legs 2 and 3, and suitable lids 4, 5 and 6. The grate bars ofthe stove may be permitted to remain therein, and are indicated at 7 This burner has its pipes secured to a plate 8, which plate is of a convenient size to place within any suitable stove, the space around the edges of the plate bein packed with asbestos fire clay as indicated at 9 to compel all of the air passing'to the burner to pass through the two holes 10 and 11 in the. plate 8. The plate 8 has suitable holes at its center to receive two pipes 13 and 14, which pipes may be forced thereinto, and which are bent to pro duce the horizontally extending members 15, 16 and 17 within the fire box, the pipe '13 being similarly bent to produce the horizontal members 15', 16 and 17' within the fire box.

i From a point adjacent the top of the plate in each of the pipes 13 and 14, 'a series of wires 19 filling said pipes extend around through the members 15 whereby the vaporization thereof is accelerated. The oil escapes from the pipes 17 and 17 at small openings 20, 20.over the holes flame from heating said pipes red hot, since and 16 to assist in- .delivering the heat tothe oil being burned the flame will strike the deflector plates and be thrown to one side or the other as the-case maybe. 7

In addition to the deflectors 21, 22, there are two other deflectors 25, 26 on the pipes 16 and 16, which deflectors are ordinarily turned up to the position shown-in Fig. 1 and out of use. When it is desired to quickly heat the oven, the deflectors 21 and 22 are pushed out of the way of the direct flame making room for the larger deflectors 25 and 26, which latter are then placed over the flames and tilted to direct the flame in the bestv direction to heat the oven or the top of the stove quickly. The deflectors 21. and 22 are smaller than the deflectors 25 and 26 and are more suitable for ordinary 10W fires since they do not obstruct the flame so much as the larger .spreaders which are used when a more extended flame is to be directed around thedoven and without an increase in the fuel use When the oven is to be heated, the deflectors 25, 26 are turned to direct the flame back (Fig. 2) and when the top of the stove is to be heated they are tilted so as to cause the flame to move forwardly, (Fig. 1), and thereby give a better effect on the top of the stove. y

In order to make it possible to turn the fire down without altering the burning conditions at each flame, the pipes 27, 28 which are connected to the pipes 13, 14:, have a three way valve 29 at their front ends. The

valve 29 has a plug 30 with suitable passages to permit the oil to be turned'to either or both of the pipes 27, 28, as may be desired, and it is operateclby means of the handle 31 on the valve stem 32. Below the three way valvethere is a pipe 33 and. a needle valve 34 to regulate the quantity of oil supplied to the burner.'

In operation, the burner is started by throwing a small piece of newspaper into the fire box under the pipes 15, 16. The heat from the paper is suflicient to cause the generation of gas in the pipes 15 and 16, and as the gas issues from the openings 20 it is completely vaporized and burns substantially without a carbon deposit.

It will be noted that it is essential to properly space the deflectors away from the pipes supportingthem so asto leave a considerable air space to prevent the pipes from becoming so hot as to cause a carbon deposit therein.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is as fol-v lows:

1. An oil burner comprising a plate adapted to support a burner within a fire box, a

. pipe passing through said plate and having a plurality of vertically superposed horizontally extending members, the lower of which has a fuel escape opening, a'reversible double deflector carried by one of said members to prevent the flame from striking, two of the oil supply members directly, and means to control the fuel supply.

w 2. An oil burner comprising a plate adaptedto support the burner within a firebox, a pipe passing through the plate and having a plurality of vertically superposed horizontally extending members the lower of which has a fuel escape opening, a reversible doubledeflector to prevent the flame from directly striking two of the horizontally extending members, a heat transfer filling in said pipes and a fuel'sup 1y valve.

In testimony whereof have hereunto Set my hand this 25th'day of February, A. D.
